The tentacle wine bottle stopper will prevent wine spillage. The stoppers, made by NeatoShop, are shaped to look like a slimy tentacle. Each stopper is handmade and uniquely painted, so no two are exactly alike.

Another really cool bottle stopper is the justmustard caps lock bottle stoppers (http://www.justmustard.com/product-118/caps-lock/). A little more geeky, but work really well thanks to three seals which mean you can use them on bottles with different neck widths.
